SmartScreen Filter: frequently asked questions

Applies to Windows 7

SmartScreen Filter is a feature in Internet Explorer that helps detect phishing websites. SmartScreen Filter can also help protect you from downloading or installing malware (malicious software).

SmartScreen Filter helps to protect you in three ways:

As you browse the web, it analyses webpages and determines if they have any characteristics that might be suspicious. If it finds suspicious webpages, SmartScreen will display a message giving you an opportunity to provide feedback and advising you to proceed with caution.

SmartScreen Filter checks the sites you visit against a dynamic list of reported phishing sites and malicious software sites. If it finds a match, SmartScreen Filter will show you a warning notifying you that the site has been blocked for your safety.

SmartScreen Filter checks files that you download from the web against a list of reported malicious software sites and programs known to be unsafe. If it finds a match, SmartScreen Filter will warn you that the download has been blocked for your safety. SmartScreen Filter also checks the files that you download against a list of files that are well known and downloaded by many Internet Explorer users. If the file that you're downloading isn't on that list, SmartScreen Filter will warn you.

Use of SmartScreen Filter is governed by the Microsoft Service Agreement. For more information, read the Microsoft Service Agreement online.

When you download a program from the Internet, SmartScreen Filter will check the program against a list of programs that are downloaded by a significant number of other Internet Explorer users and a list of programs that are known to be unsafe. If the program you're downloading isn't on either list, SmartScreen Filter will display a warning that the file isn't "commonly downloaded." It doesn't necessarily mean the website is fraudulent or that the program is malware, but you probably shouldn't download or install the program unless you trust the website and the publisher.

From the warning page, you can choose to report this site as a safe site. Click More information, and then click the Report that this site does not contain threats link to go online to the Microsoft feedback website, and then follow the instructions.
